Human Heart Anatomy

Human Heart Anatomy

Locate, illustrate and label the following features of the human heart and the circulatory system of the cat. The page numbers refer to Gilbert’s Pictorial Anatomy of the Cat.

Make two illustrations of the dissected human heart:
    I. Features of the human heart, right half
    II. Features of the human heart, left ventricle
